1acc5559d9 snowball: Clear UART RX FIFO
Without usb-serial cable plugged at this stage, some
garbage is seen in UART RX FIFO, which blocks autoboot
progress. The fix makes sure to empty the RX FIFO,
before we wait for user input to interrupt autoboot.

10ed93dcdd u8500: Separating mmc config parameters from driver
Configuration in vexpress and u8500.v1 is different from what
is needed in u8500.v2.  As such, card configuration specifics need
to reside in the board file rather than the driver.

1e37322e5a u8500: Moving processor-specific functions to cpu area.
Functions such as providing power to the MMC device and reading
the processor version register should be in the cpu area for
access by multiple u8500-based boards.

9660e442de cosmetic: s/BOARD_LATE_INIT/CONFIG_BOARD_LATE_INIT
This renames BOARD_LATE_INIT to CONFIG_BOARD_LATE_INIT.
Along the way it removes some leftover

 #define BOARD_LATE_INIT		1

and adds some basic documentation for board specific
callbacks in README.

464c79207c punt unused clean/distclean targets
The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used.  Punt them all.

MAKEALL didn't report any errors related to this that I could see.
